AIR=DISTRIBUTER FOR CENTRAL DRAFT LAMPS.

SPECIFICATION forming part of Letters Patent No. 529,496, dated November20, 1894.

Serial No. 458,449. (No model- To aZZ whom it may concern:

Be it known that I, JOSEPH J AUOH, of Meriden, in the county of NewHaven and State of Connecticut, have invented new Improvements inAir-Distributors for Central-Draft Lamps; and I do hereby declarethefollowing, when taken in connection with the accompanying drawingsand the letters of reference marked thereon, to be a full, clear, andexact to description of the same, and which said drawings constitutepart of this specification, and represent, in-

Figure 1, a View in side elevation of one form which an air-distributorconstructed in :5 accordance with my invention may assume; Fig. 2, aview partly in elevation and partly in vertical section of one of themodified forms which myimproved air-distributer may assume; Fig. 3, adetached plan view of the deflector of the air distributer shown in thepreceding figure; Fig. 4, a view in side elevation of another form whichmy improved airdistributer may assume.

My invention relates to an improvement in air-distributors or thimblesfor central-draft lamps, the object being to produce a simple andeffective device.

\Vith these ends in view, my invention consists in an air-distributerhaving certain de- 0 tails of construction as will be hereinafterdescribed, and pointed out in the claim.

Air'distributers constructed in accordance with my invention may assumedifierent forms, three of which I have shown in the ac- 3 5 companyingdrawings.

As shown in Fig. 1 of the drawings, the distributer consists of a tubeC, formed with fine lateral perforationsc, and having an enlarged,integral, concentric, imperforate base C,

40 adapted to support the distributor within the central draft-tube ofthe lamp in which the distributer is used. Two horizontal annular beadsor shoulders c 0 located near the upper end of the tube in the midst ofits perfora- 4 5 tions, and themselves perforated, are formed byupsetting the tube outwardly. They receive between them the inner edgeof an annular deflector D, located in a horizontal plane, and consistingof a flat sheet-metal ring. The diameter of the entire portion of thetube above the said deflector is smaller than the diameter of thedeflector, and the diameter of that portion of the tube immediatelybelow the deflector is also smaller than the diameter of the deflector.The fiat upper end or top of the tube is closed and imperforate.

The air-distributor shown by Fig. 2 of the drawings consists of a tubeE, formed with fine lateral perforations e, and having an en- 6c larged,integral, concentric, im perforate base E, adapted in diameter tosupport the distributor within the central-draft tube of a lamp. Thesaid tube E is provided at its upper end with two horizontal shoulders e6 formed in the midst of its perforations, the shoulder 6 beinguppermost, and produced by upsetting the tube, and the shoulder e beingformed by reducing the upper end of the tube in diameter at a pointbelow the shoulder c. The said shoulders are separated just enough toreceive between them the innor edge of an annular deflector F, which isby preference furnished with vertically arranged perforations, as shownin Fig. 3. In this figure of the drawings the tube E is shown by fulllines to be of substantially uniform diameter between its shoulder e andits base E, and by broken lines to have a deep Wide annular grooveformed between such points. The flat upperend or top of the tube isclosed and imperforate.

The construction shown by Fig. 4 of the drawings has an enlarged,imperforate base G, and a laterally perforated tapering upper portion G,which is struck out just above its center to form two horizontal annularbeads or shoulders g g, separatedjust enough to receive the annulardeflector Hbetween them.

My improved distributor in its provision with two annular shouldersformed in the midst of its perforations, for confining a deflector inplace, is very simple in construction, and requires no solder, which,when used, is liable to stop up the perforations. I have 5 found it,moreover, a very effective air-distributer in use.

By preference, the deflector will be provided with verticalperforations, as shown in Fig. 3, which permit a portion of the air toto: pass upward to the flame, whereby the body of air is reduced so muchin volume and force, that it will not be thrown radially outward farenough beyond the'edge of the deflector to sulphurize and cloud thechimney. Furthermore, the combined action of the perforations in thetube, and the deflector, so sifts the air into fine currents and breaksthe force of the draft, and handles the currents, as to produce a flamenot only white and constant, but very even on top. The three forms shownand described herein, of my improved air-distributer, are designed totake all of the air rising through the draft-tube, but that is notessential, though I intend that the major portion, at least, of the airpassing through the draft-tube shall be taken by the distributer.

In view of thedifferent forms shown and described, I would have itunderstood that I do not limit myself to the exact forms set forth, buthold myself at liberty to make such changes and modifications as fairlyfall within the spirit and scope of my invention.

I am aware that it is old to form inwardly projecting horizontalshoulders in the midst of the perforations of an air-distributer toconfine an internal annular deflec or by its outer edge. I do not,therefore, broadly claim securing the deflector in place by means ofshoulders formed in the distributer and located so as to hold thedeflector between them. I am also aware that it is old to locate anoutwardly projecting perforated annular deflector upon a distributerconstructed with perforations, and I do not therefore claim thatconstruction broadly.

Iam further aware that it is old to construct a distributer forcentral-draft lamps from a long tube furnished atits lowerend withradial wings which engage with the inner face of the draft-tube forsupporting the distributor in place therein, and the said tube havingits upper end perforated and furnished with three outwardly projectingannular deflectors, of which the lower deflector is imperforate andlocated between the perforate and im perforate portions of the tube, andof which the upper deflector is perforate and located close to the upperend of the tube, and of which the middle deflector is imperforate andlocated close to the perforate upper deflector.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The herein described air-distributer for central-draft lamps, having itsupper end closed and constructed with two exterior horizontal shouldersformed near but below its said closed upper end in the midst of itsperforations, and provided with a single exterior annular deflectorconfined by its inner edge between the said shoulders, located in ahorizontal plane and consisting of a flat sheetmetal ring, the diameterof the entire portion of the distributcr above the said deflector beingsmaller than the diameter of the deflector,

and the diameter of that portion of the distributer immediately belowthe deflector being also smaller than the diameter of the deflector, andthe lower end of the distributer being adapted to be supported withinthe central draft-tube of a lamp, and to take the major part of the airpassing through the same, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

JOSEPH JAUQI'I.
